From and Endura T22 (great for beginners!). To this with a Predator mod. Been going for a few weeks now and I love it! Love the clouds (never wanted to get into that, but it's so damn satisfying). And the flavour is as big as the clouds! It uses more juice than I was used to, but I guess that's sub ohm for you.
There's only one possible negative. The juice that you enjoyed on a smaller mod (1 ohm+) might taste totally different. That being said, it could improve a thousand fold.
Personal examples. I had an RY4 blend I was stoked with. Perfect. Smooth, nutty with a slight sweet finish. With this tank, it's the same for the first few puffs. Then slowly gets sweeter and sweeter. Until it's just gross.
On the flip side, my mint/menthol is fantastic! Tank after tank.
Either way, it's great tank. Doesn't leak (and I'm pretty casual about leaving it in the car etc). Both the 0.25 and 0.5 coils are great. Easy to use, fill and clean. Oh and the air flow is brilliant. I can't use my old T22 anymore. Got 2 of these now, for flavour changes.
Tl:Dr Great tank. Great for your first Sub Ohm too.
